3. All Rights Reserved © Alcatel-Lucent 2006, ##### 3 | Presentation Title | Month 2006 What are our Objectives? (a review)  Support subscriber access networks using point to multipoint topologies on optical fiber  PHY(s) to have a BER better than or equal to 10-12 at the PHY service interface  Provide physical layer specifications:  PHY for PON, 10 Gbps downstream/1 Gbps upstream, single SM fiber  PHY for PON, 10 Gbps downstream/10 Gbps upstream, single SM fiber  Define up to 3 optical power budgets that support split ratios of 1:16 and 1:32, and distances of at least 10 and at least 20 km. Also from our PAR  The scope of this project is to amend IEEE Std 802.3 to add physical layer specifications and management parameters for symmetric and/or asymmetric operation at 10 Gb/s on point-to-multipoint passive optical networks.

Traditional data access networks are asymmetrical  DSL  Cable Modem  Credible Rumors  “lowest-asymmetry point when Kazaa and Napster became popular (1:1.4), but now with introduction of IP video like YouTube it is becoming more asymmetric …”  In July of last year, YouTube reported 65,000 uploads per day and 100 Million (!) downloads. This is roughly 1:1500 traffic ratio. But not all  P2P Ethernet This has not been the case with Enterprise networks (Ethernets dominant market) We need to be consistent with our earlier efforts from EFM

6. All Rights Reserved © Alcatel-Lucent 2006, ##### 6 | Presentation Title | Month 2006 Introducing the Simplex PMD Every communication link must have at least one transmitter and one receiver. In order to achieve bi-directional communications both nodes must have at least one transmitter and one receiver It is proposed that, for 10G EPON we define PMDs as Simplex links, one transmitter paired with one receiver that, when coupled via a PON ODN form a simplex communications link. Components would then be composed of at lease one transmitter and one receiver, for PON these will always be from different PMDs (the downstream direction is always continuous whereas the upstream is always burst mode) Old PMD definitionProposed PMD definition

7. All Rights Reserved © Alcatel-Lucent 2006, ##### 7 | Presentation Title | Month 2006 Some Definitions From the Worlds Leading WEBpedia  Half Duplex  A half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously).  Full Duplex  A full-duplex system allows communication in both directions, and unlike half- duplex, allows this to happen simultaneously.  Simplex  There are two (contradictory) definitions that have been used for the term. In both cases, the other definition is referred to as half duplex.  1) One way at a time: According to the ITU-T definition, a simplex circuit is one where all signals can flow in only one direction at a time.  2) One way only: According to the ANSI definition, a simplex circuit is one where all signals can flow in only one direction.

8. All Rights Reserved © Alcatel-Lucent 2006, ##### 8 | Presentation Title | Month 2006 Some More Definitions From Other (more credible) Sources:  IEEE – Half Duplex: A mode of operation of a CSMA/CD local area network (LAN) in which DTEs contend for access to a shared medium. Multiple, simultaneous transmissions in a half duplex mode CSMA/CD LAN result in interference, requiring resolution by the CSMA/CD access control protocol.  ITU – Simplex: a simplex circuit is one where all signals can flow in only one direction at a time  ANSI – Simplex: a simplex circuit is one where all signals can flow in only one direction

Rate  1000(1 x 10e9)  10G(10 x 10e9)  But 1000/10G is a bit awkward Line Code  X8B/10B coded  R64B/66B coded  We will use both, but never for the same rate Wavelength  L 1310 nm  E1550 nm  ?1490 nm  1490 seems to have been orphaned, and what of 1530 nm or 1580 nm? Reach  1010 km  2020 km  3030 km? Transmit Direction  DDownstream  UUpstream This is after all PON  PPON  BASESome traditions are inviolate
